I'm still in the process of collecting/analyzing our FE, but (so far) I've been leaving the Prius in Cruise-Control going UP hills then "coasting" (trans in Neutral) whenever possible.

My (yet to be proven) thought-process is: (a) let the ECU software optimize engine/battery usage going UP hill and then (b) let the vehicle inertia "coast" for as long as possible going DOWN hill with NEITHER battery NOR ICE usage...and sparingly use the regeneration-braking to maintain velocity within posted-speed limit.
